Rapid fossilization of fishes and other animals in the Lower Cretaceous of the Chapada do Araripe, north-east Brazil, has preserved the most delicate structures known in the fossil record. Gills, muscles, stomachs and even eggs with yolks have been found. Interestingly, the material is not particularly rare, and specimens can be purchased from your local rock shop.
